The high DC voltage output Airdolphin GTO (Grid-Tie Optimized) is our latest small wind turbine model, rated 1.1 kW at 12.5 m/s (27 mph) with peak instantaneous output reaching 4 kW at 20 m/s (44 mph). The Airdolphin GTO connects to the utility grid via Grid-Tie inverters. Supported by its unique Intelligent Power Management System, the unit maintains seamless operation from a cut-in wind speed of just 2.5 m/s (5.3 mph) to extremely windy conditions. Weighing less than 20 kg (42.9 lbs.) with a rotor diameter of only 1.8 m (6"), the Airdolphin GTO is the most efficient and easily installed small wind turbine in this class. Zephyr's Airdolphin Series is engineered and tested for reliability under every condition, providing years of maintenance-free operation.
